--- Comment #4 from Jiri Slaby <jirisl...@gmail.com> --- It's because QFont::fromString(const QString &descrip) doesn't OR the QFont::resolve_mask with QFont::StyleNameResolved the same as QFont::setStyleName(const QString &styleName) does. So this is an upstream (Qt) bug. Reproducer: ================ $ cat main.cpp #include <QApplication> #include <QDebug> #include <QLabel> #include <QDialog> static void setLabelFont(QLabel &label, const QFont &font) { qDebug() << __func__ << font << "style" << font.style() << "stylename" << font.styleName() << "resolve" << QString::number(font.resolve(), 16); label.setFont(font); label.setText(font.toString()); } int main(int argc, char *argv[]) { QApplication a(argc, argv); QDialog w; QLabel label1(&w), label2(&w); QFont font1; font1.fromString("Misc Fixed,10,-1,5,57,0,0,0,0,0,SemiCondensed"); auto font2 = font1; #if 1 font2.resolve(font2.resolve() | QFont::ResolveProperties::StyleNameResolved); #else font2.setStyleName("SemiCondensed"); #endif setLabelFont(label1, font1); setLabelFont(label2, font2); w.show(); label2.move(0, label1.size().height() + 5); w.resize(label1.size().width(), label2.pos().y() + label2.size().height()); return a.exec(); } ================ $ cat Makefile COMPONENTS=Qt5Core Qt5Gui Qt5Widgets CXXFLAGS=$(shell pkg-config --cflags $(COMPONENTS)) -Wall -Og -g LDLIBS=$(shell pkg-config --libs $(COMPONENTS)) -flto all: main ================ Both labels are with the same font, the latter sets the resolve_mask and is shown correctly. -- You are receiving this mail because: You are watching all bug changes.
